Background: Asymptomatic cryptococcal antigenemia is a state of cryptococcal infection commonly seen in immunocompromised HIV-infected persons. Without early intervention, a proportion of HIV-infected persons with cryptococcal antigenemia may go on to develop cryptococcosis, especially cryptococcal meningitis, which is associated with high mortality. The benefits of antifungal intervention and optimal therapeutic intervention regimens for HIV-infected persons with cryptococcal antigenemia remain controversial. We therefore designed the present study in order to investigate the necessity of, and the optimal regimens for antifungal intervention in the clinical management of cryptococcal antigenemia in HIV-infected populations. Methods/Design: This study will be an open-labeled, multi-center, prospective, randomized controlled trial, and 450 eligible participants will be randomized into a control arm and 2 intervention arms at a 1:1:1 ratio, with 150 subjects in each arm. Participants in the control arm will not receive antifungal treatment during the study period. Participants in intervention arm 1 will receive oral fluconazole 800 mg/day for 2 weeks, followed by 400 mg/day for 8 weeks and 200 mg/day for 42 weeks, and participants in intervention arm 2 will receive oral fluconazole 400 mg/day for 52 weeks. The primary outcome is the incidence of CM among the 3 groups during the study period. The secondary outcomes include the differences in all-cause mortality, proportion of patients reverting to blood CrAg negativity, change of CrAg titers, and adverse events among the 3 groups during the follow-up period. Discussion: We envisage that the results of this study will reveal the necessity of, and the optimal therapeutic regimens for, antifungal intervention in clinical management of HIV-infected patients with cryptococcal antigenemia. Trial registration: The study was registered as one of the 12 clinical trials under a general project at the Chinese Clinical Trial Registry on February 1, 2019, and the registration number of the general project is ChiCTR1900021195.
